Review

Wow!
Style: Canon | Verified Purchase
I used these tubes along with my Canon 35mm macro lens. Totally crazy. You must realize that the depth of field will be very shallow. You might try to focus for the first time and think there's something wrong. You must move the camera close to your subject until you reach the depth of field zone. Here are some pictures I took down at Home depot garden center and other places around Honolulu. Some with just the macro lens and some with the macro and these tubes. They work good with regular lenses too. The shorter the lens, the closer you can get. The longer the lens, the further away the minimum focal distance but you lose magnification. A 18-55 is ideal.

If you really want to get into macro, you gotta get a dedicated macro lens. The canon 35mm is only $300. And it has the ring light in the front to light up your subject. Get that lens and these tubes and you will be a happy camper. If you only have the tubes, you won't be able to focus outside of the very shallow depth of field zone. With a macro lens you can focus to infinity and do macro too.
 
Outstanding
Style: Canon | Verified Purchase
I wasn't real sure how these were going to work out....

Gotta say that I'm well pleased with this set.

I don't shoot a lot of macro...certainly not enough to justify a dedicated macro lens.
But I figured adding some extension tubes to my bag might give me a couple more options when needed...
Just before I almost purchased the OEM tubes...I figured, "What the heck...these are cheap & seem to be well regarded...worst case; they dont work and I'll send 'em back."
Well I'm happy to say that they work GREAT.

I can maitain AF for the most part and exposure is a no-brainer.
They attach nicely and generally feel solid. Not up to Canon feel & weight (or build)...but certainly acceptable for my use.
The electronics work just fine.
The caps are fairly cheap so I replaced those with Canon caps because they're a bit more robust. Though the ones provided are probably more than adequate. That's just me.

Like I said, I don't shoot a lot of macro stuff...but just the other day needed to shoot a couple of watches...
These worked a treat and the watches are gone (sold)...so the set is more or less paid for. Score.

And it was only after I started looking that I discovered that Kenko has been around since like 1957. O_o
I guess I never caught on that Kenko is Kenko Tokina...and they own several other companies like Slik & Tasco...such it the way of things when one is focused on only a few brands. Now I know.

Regardless, these are well worth considering.
 
A solid alternative to OEM extension tubes
Style: Canon | Verified Purchase
These have a nice heft to them. They are just empty tubes, so there is no effect on image quality, but understand that these are for macro photography and you will lose the ability to focus at infinity. The most important thing with this type of extension tube is having the electronics from your lenses working through them without problems. I tried the 3 tubes in different combinations and had no issues whatsoever. They mount to the camera with a solid feel and have no play. They are substantial enough in construction that I have no fears of a heavy lens breaking them. You get a set of 3 tubes for what you would pay for 1 Canon tube.
 
Worth the purchase
Style: Canon | Verified Purchase
I absolutely love this set of extension tubes. I use them with a Canon 90D along with my 50mm lens and they allow me to get really close to the subject. I wasn't sure I wanted to get into macro photography and if you're in the same boat as me then this is definitely the way to go for the price. All the example photos attached are using the 12mm extension tube along with the 50mm lens. You can get even closer if you stack the tubes and have lots of flexibility with pairing the different ones (12, 20 and 36mm). Having lots of fun with them, hope you do too!
 
Crisp and vivid! Outstanding!
Style: Canon | Verified Purchase
I have a Canon 80D and I'm using my Canon 100-400 ii for "pseudo" macro photography which already worked impressively well.

But using these extension tubes is the icing on the cake. I only used the 36mm and got amazing results! Crisp and vivid and auto focus works perfectly!

Highly recommend!
 
Great for Professional Results with Macro Photography!
Style: Canon | Verified Purchase
 I recently purchase these Kenko extension tubes for my Canon 5D Mark II and have found them to work best with my 24-105mm lens. Although the autofocus does not work with this lens when using these tubes the results are spectacular.

The extension tubes are very well made and connect together perfectly. I am not concerned with connecting any of my Canon L lenses to these tubes and am now considering purchase of another fixed focal length lens to combine with these for even more spectacular results.

This has opened a whole new world for my nature photography and has rejuvenated my spirit for exploration in the macro world!
 
Great Extension Tubes.
Style: Canon | Verified Purchase
After being disappointed with a Neewer model of Extension Tubes I purchased these Kenko models and haven't stopped yet. They do a great job for macro photography. I have been using them for several weeks and am very pleased with the photographs that I have taken with this product. It's true that you get what you pay for and I recommend that folks don't waster their time with the cheap macro tubes and invest in good ones like these.
 
An introduction to macro photography
Style: Canon | Verified Purchase
I am sure that once you decide to journey into the world of professional macro photography you will probably want to go ahead and invest in something a little more permanent than these Kenko extension tubes, however for the amateur like myself these Kenko extension tubes are a great starting point.

When you pop these out of the box, your first thought may be "Why the heck do they cost over a hundred bucks?" and honestly I think it'd be a fair question. Other than the fact that it seems like all items having to do with photography come with huge price tags, I'm not really sure. The body of the extension tubes are mostly plastic with metal rings and screws at the end caps - that's really about it. I will say that the machining of each piece is very precise, I had no flash or bits of plastic left over on the edges anywhere and the contacts for the auto-focus connections were flawless and worked perfectly. But when it's all over and done with, these are pretty much just plastic tubes with circuit contacts.

But are they worth it?

Well, when the other option is to go out and buy hundreds (thousands) of dollars worth of macro-specific lenses in order to dabble in macro photography, then yes. And if the only other option is to buy a single "name brand" extension tube which costs as much as this set of three, then yes. There is nothing wrong with these Kenko extension tubes and I will admit to having a lot of fun when using them and they work great, but there are a couple of things to keep in mind...

1 - Do you really need the auto focus to work while working with macro photography?
I sort of regret paying for the extra autofocus feature on these tubes because honestly, you're probably doing most of your focusing manually. "Fast" and "handheld" usually does not go together in the same sentence as "macro photography". Now having said that, two of my customer example photos were taken by hand - but they were also taken in burst mode and I had at least ten to fifteen rejected shots before I found a nice sharply focused shot that I liked.

2 - Are you going to get serious about photography? (Or are you in a class?)
These extension tubes will literally "extend" the usefulness of your basic lens set, but they are not a replacement for a good macro-capable lens. If you're thinking that you're going to do a lot of macro photography or that you'll upgrade to a full macro lens in the future, you may want to skip the tubes altogether and save up for the glass instead.

Now, if you're an amateur like me who likes to dabble in photography and likes to play with toys, then absolutely - get these extension tubes. They're a heck of a lot of fun and allow you to take those really awesome close up shots without having to spend hundreds of dollars buying macro-specific glass. If you want to save even more money I think the non-autofocus enabled versions are worth a serious consideration.
 
For the occasional macro shot or the need to get closer with any lens
Style: Canon | Verified Purchase
Kenko Auto Extension Tube Set is well made for fit and the finish is excellent. All tubes are well marked easy to see and the locking lever is ergonomic. Overall they look good and function well.
 
Fantastic Value; Doesn't Distort or Interfere with Autofocus
Style: Canon | Verified Purchase
I purchased this extender set as a cheaper alternative to a dedicated Macro lens; with these, I can reduce my minimum focus distance and get in a lot closer for the picture. What I love about Kenko's, as opposed to cheaper alternatives, is that they include the electronic circuitry that enables my lenses' autofocus to still perform.

These are high quality, on par with the Canon version, but a lot cheaper and more versatile. As with all extenders, these work best with shorter focal lengths; I tend to use them on 50mm or shorter, and switch to a close-up lens (such as the  Canon 500D ) when using longer lengths such as my 85mm prime or my telezoom. Highly recommended.

Custom Questions & answers

Question:Do these tubes have lenses in them
Answer:no it is an extension tubes
 
Question:Could you put a couple of 2x ext. with the use of these tubes ?
Answer:Yes you can stack them. Just be prepared for the light dropoff and the heavy vignetting.
 
Question:does this work with the canon 6D?
Answer:Don't know; but I do know they work great on my Canon Rebel 4Ti 650D. If they work on one Canon, I'm assuming the set would work on other Canons. Find a camera store and try it. B. Morgan
 
Question:Can i use it with 10mm - 22mm lens
Answer:Should be able to but keep in mind, only part of your focal range will be usable. Maybe only the upper 1/2 or 1/3 . . . The rest of your range will never be brought into focus. The extension tubes limit the functionality of your lenses.
 
Question:Will these extension tubes work for a Canon 80D ?
Answer:They work with EF and EFS lenses. I have a canon 60D. I would think the format is the same.
 
Question:Can i stack 2 kenko ext tube of 68mm to have better macro capability. Canon 70D 50mm f1.8. Would it work and what would be min dist to focus frm lens?
Answer:You can stack them together, but the image quality won't be worth it; probably unusable. Even if you're able to boost light as much as you can and stop down to F22, edge sharpness would be nearly nonexistent. Focal distance at that point may be the least of your worries.
 
Question:Would it work with a canon body 5d Classic with a 50mm 1.8?
Answer:It should
 
Question:Can these tubes be used with a telephoto lens?
Answer:Yes the extension tubes can be used on a telephoto lens. It makes the subject look closer on the sensor.
 
Question:I am stating Macro for a hobby, Would these work on a 70mm 200mm 2.8?
Answer:I have both the extension tubes and a 70-200mm f2.8 lens. I can't say I have tried the tubes on this lens but I see no reason for it not to work.
 
Question:Will it work with canon 7D
Answer:Yes, I believe it will. It works with my Canon 6D which is full frame, but that should not matter. I found the Kenko Set to be a good value.
